Data availability
Every release is publicly available on the Registry of Open Data on AWS, in the S3 bucket below. No AWS account or credentials are needed. Each release is one folder of Delta Lake tables (Parquet files plus _delta_log/), named the same as its page above.
- Bucket
s3://connects-common-connectivity/- ARN
arn:aws:s3:::connects-common-connectivity- Region
us-west-2- Browse
- List releases (opens the bucket listing in your browser)
Browse
With the AWS CLI, add --no-sign-request to skip credentials:
# list releases, then the tables in one release
aws s3 ls --no-sign-request s3://connects-common-connectivity/
aws s3 ls --no-sign-request s3://connects-common-connectivity/ccm_v1.0.1_data_202611_v2/
Download
Copy a whole release, keeping its folder layout intact so the Delta logs still match their files:
aws s3 sync --no-sign-request \
s3://connects-common-connectivity/ccm_v1.0.1_data_202611_v2/ ./ccm_v1.0.1_data_202611_v2/
Read without downloading
Delta readers can also read straight from S3. Always read through the Delta log (Polars, deltalake, Spark, DuckDB delta_scan), not with pandas.read_parquet on the folder.
import polars as pl
opts = {"aws_region": "us-west-2", "aws_skip_signature": "true"}
cells = pl.read_delta("s3://connects-common-connectivity/ccm_v1.0.1_data_202611_v2/dataitem", storage_options=opts)
